GEM-4D: Geometry-Enhanced Video World Models for Robot Manipulation

GEM-4D, a new geometry-enhanced video world model, has been introduced to improve robot manipulation by addressing the limitations of existing video world models that struggle with consistent physical point tracking over time. This model incorporates dense 4D correspondence supervision from a pretrained geometry foundation model, allowing it to generate videos that are both visually plausible and physically grounded for reliable action execution.
